Abstract :
A transducer that uses an intensity-modulated optical method to measure force is described in this paper. The method relies on the additional optical power loss induced by the compression of a fiber optic loop. The sensor is shown to exhibit long-term stability. Using a simple recalibration procedure, a repeatability of ±0.5% was obtained
